+```ts
+function dehydrate(client, options): DehydratedState;
+```
+
+Defined in: [packages/query-core/src/hydration.ts:207](https://github.com/TanStack/query/blob/main/packages/query-core/src/hydration.ts#L207)
+
+Dehydrates a `QueryClient`'s cache (queries and mutations) into a plain, serializable `DehydratedState`,
+typically to embed in server-rendered markup and later restore into a client-side `QueryClient` via `hydrate`.
+Which queries/mutations are included, and how their data/errors are transformed, is controlled by `options`,
+falling back to the client's `dehydrate` default options, and finally to `defaultShouldDehydrateQuery` /
+`defaultShouldDehydrateMutation`.
+
+## Parameters
+
+### client
+
+`QueryClient`
+
+### options
+
+[`DehydrateOptions`](../interfaces/DehydrateOptions.md) = `{}`
+
+## Returns
+
+[`DehydratedState`](../interfaces/DehydratedState.md)
+
+## Example
+
+```ts
+const queryClient = new QueryClient()
+
+await queryClient.prefetchQuery({
+  queryKey: ['posts'],
+  queryFn: getPosts,
+})
+
+const dehydratedState = dehydrate(queryClient)
+```
